报告摘要：
Selecting effective corrosion inhibitors from the vast chemical space is not a trivial task, as it is essentially infinite. Fortunately, machine learning techniques have shown great potential in generating shortlists of inhibitor candidates prior to deeper experimental testing. This work showcases the promise of computer-assisted methods for rapidly and efficiently screen large numbers of organic compounds as potential corrosion modulators for light Mg and Al alloys. Two data-driven quantitative structure-property relationship (QSPR) machine learning models were trained and used for in silico searches. Statistical methods were applied to select the most relevant features to the target property for support vector regression and kernel ridge regression models, respectively, to predict the behavior of untested compounds. The performance of the two supervised learning approaches were compared and the robustness of the data-driven models were assessed by experimental blind testing.
The active learning approach was implemented in order to improve the quality of prediction via inclusion of the experimental results of the newly predicted modulators into extended training data sets. The applicability of the suggested models for both selection of corrosion inhibitors and electrolyte additives for primary Mg-batteries has been demonstrated.
